. This invention relates to an improved fuel vaporizer forinternal combustion engines such as are generally used upon automobiles and has for its rimary object to provide means whereby the engine may be initially started on gasolene as a fuel, and kerosene or other relatively crude and inexpensive oils subsequently employed for the operation of the engine.

It is another and more particular object of the invention to provide a device for the above purpose including a tank having gasolene and kerosene compartments, a pipe coil engaged upon the exhaust pipe of the engine and connected at its ends to the respective compartments, a conduit connected to one end of the pipe coil and extending through the carburetor, and a three-way valve operable to supply the gasolene or vaporized kerosene to the carburetor.

lit is a further general object of the invention to provide a device for the 'above purpose which is exceedingly simple and inexpensive'in its construction, highly reliable and efiicient in practical use, and will result in considerable economy in the consumption of fuel.

With the above and other objects in view, my invention consists in the novel features of construction, combination and .arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a perspective View illustrating the preferred embodiment of the'invention; Fig. 2 is a horizontal section showing the three-way valve in position to supply gasolene to the carburetor; and

Fig. 3 is a similar view showing said valv in position to supply the vaporized kerosene to the carburetor. 7

Referring in detail to the drawing, 5 designates a tank or reservoir which may be is closely coiled, as at suitably mounted upon a vehicle body and is prov ded with an internal partition wall 6 dividing the same into a gasolene chamber 7 and a kerosene chamber 8, the latter constituting the greater portion of the interior areaof the tank. Each of these fuel receiving at its top and an. outlet pipe 9 and 10 respectively at itsbottom.

To the outlet pipes 9 and 10, the pipes 11 are connected, said pipes extending horizontally and each having a depending pipe section 12 coupled to its outer end. Each of the couplings is provided with a suitable valve, indicated at 13, whereby the supply of fuel from the compartments or chambers of the tank may be controlled.

A length of tubing,

14;, and engaged upon the exhaust pi e of the engine indicated at P. One end oi this copper tube is extended, as at 15, and coupled to the pipe 12 oi the kerosene chamber 8. The other end of said coiled tube is also extended, as at 16, and similarly coupled to the pipe 12 of the gaso lene chamber 7. To this latter end portion of the tube, a pipe or conduit 17 is connected by means of a T-coupling 18 and extends to the carbureter. A rotary three-way valve 19 engine in starting the operation of the same,

Atterthe engine has been properly started,

the valve is turned or rotated by any suitable means under the control of the operator, to the position shown in Fig, 3, wherein one of the'valve ports is in communication with the end of the pipe coil it and another in communication with the conduit 17,? whilecommunication between said co-n- 'duit and the portion 1 6 of the pipe coil which leads to the gasolene chamber is cut oil by the valve member. The-kerosene flowing through the coiled tube it is highly heated and vaporized so that it will pass from said coil throughthe conduit tooa suitpreterably of copper,

Thus, gasolene ing chambers is provided with a feed openable magazine chamber to be mixed with the proper proportion of air to produce a readily combustible mixture.

From the foregoing description, taken in connection with the accompanying drawing,

the construction, manner of operation, and several advantages of my invention will be clearly and fully understood. It will be seen that I have produced a very simple and reliable device whereby, after the engine has been properly started upon gasolene, the supply of such fuel may be cut off by the operation of the valve 19 and the operation of the engine continued on kerosene as a fuel. As this latter fuel may be obtained at relatively small cost, it will be apparent that considerable economy is thus realized in the operation of automobile engines. As the kerosene is first thoroughly vaporized,

its proper combustion is assured without amper Having thus fully described my invention, what I desire to claim and secure by Letters Patent is v v In a fuel vaporizer for internal combustion engines, a fuel receptacle having separate kerosene and gasolene compartments, a discharge pipe leading from each of said compartments and providedwith a controlling valve, a coiled tube surrounding the eX- haust pipe of an engine and connected at one of its ends to the-pipe leading from the kerosene compartment, a tube connected at one of its ends to the pipe leading from the 1 gasolene compartment, a conducting pipe through which the fuel is supplied to the engine cylinders, a three-way valve connecting the other endsjof said tubes to the conducting pipe, and means for manually operating said valve to establish communication between the tube connected to the outlet pipe of the gasolene compartment and said conducting pipe, or to out OK such communication and establish communication between the coiled tube and the conducting pipe.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
